Be sure to carefully check each of those cells ( capacity, IR, Vmax, Vmin, etc).. before you wrap that pack up as they dont have the best reputation for holding their balance over time.

Auto makers secret plan to make money servicing EV's- Mach E Mustang

Oh ! Im confused...
You were comparing Ford to Tesla in the verry first line of your first post ?
So you didnt watch the video and hence you dont realise that it is impossible to use a “ trickle” charger on the Teslas 12 v aux battery !
That would be Auto design 101 failure !

James May...(yes he of ex “TopGear”)...has owned a Tesla S for some time. It is interesting what extended ownership reveals. Even, though the S was garage parked, and on a charger, the Aux 12v battery went flat and locked the car down. Solution was not as simple as you might expect, and the cause wa...

At the least you would need a replacement hub axle installed ( wheel and motor strip and rebuild !)

Re: Ebike Battery stored for a long tome

I say again..... 8-10 miles on used 10Ah Lead cells is about what you should expect. Even at their best they would only have 240 Wh of capacity on a SLOW discharge, so with aging and high rate discharge, you would be lucky to get 150-200Wh from them. (Mr Pukert wants his cut also !) so riding them n...

Re: Ebike Battery stored for a long tome

Hmm ?..... its a shame... 12 miles on used 24v SLAs was not a bad result ( dependig on the Ah rating , and your ride style etc)
But Lead is best forgotten anyway.
I would plan for 36 v Li to give you more capacity, range and speed. :wink:

Re: Hydrogen Drive - We Made the Battery Obsolete

Our system is a pressure vessel. It can safely store 600lb of hydrogen and oxygen gas, but we only store up to 300lb. We always had an air gap at the top of our electrolysis system and we had always been able to pressurize the system - in the early days they would run at 10-25lb of pressure but the...
